AB - The synthesis of a functionalized calix(4)arene bearing 1,3‐dipolaric nitrone groups (5) has been carried out. The reaction of N‐methylhydroxylamine or N‐propylhydroxylamine with the carbonyl group of 5,11,7,23‐tetraformyl‐25,26,27,28‐tetraalkoxycalix(4)arene leads to calix(4)arenes bearing a nitrone function at each of the four para‐positions. Via 1,3‐dipolar cyclo‐addition of acrylic acid methyl ester with the nitrone functions of 5, subsequently an upper rim‐substituted tetraisoxalidinecalix(4)arene is quantitatively synthesized. Further, the minimization of shrinkage of a dental filling depending on the amount of calix(4)arene‐tetranitrone is discussed. Copyright © 2011 Society of Chemical Industry
